For 132 spectra of NGC 1068 taken at 24 position angles of every 15 deg from an isophotal major axis (P.A. = 52 deg) of the inner arm region, H-alpha, H-beta, forbidden N II 6583 A, and forbidden O III 4959 A, and 5007 A, have been measured in order to present the velocity curves in tabular form. Comparisons are made with previous observations to show that these measurements are consistent with the recent observations, but inconsistent with Walker's (1986) measurements. Combined with CO velocity data, the velocity field was analyzed to reveal large-scale noncircular motions to occur within the galaxy.
